  the motif of the hierosgamos, the sacred marriage, remained the central theme of alchemy. It denotes on the one hand chemical affinity and on the other the Jungian of psychic opposites in the process of individuation, which Jung has so deeply interpreted in "The Psychology of the Transference" and Mysterium Coniunctionis.

  The hierosgamos is not a metaphor that got applied to chemistry — it ran through both registers simultaneously, which is precisely why the alchemists could not always say which they were doing. When the king and queen descend into the bath in the Rosarium series, the figures are philosophical, chemical, and erotic in the same instant. Von Franz is noting the continuity of that ambiguity into Jung's own reading: "The Psychology of the Transference" uses the same Rosarium woodcuts to think about what happens between analyst and patient, and the claim is not that this resembles sacred marriage but that the same psychic logic is at work across all three registers.
  
  What that logic is: the soul moves toward wholeness through conjunction, and conjunction requires that the opposites remain genuinely opposite long enough to actually meet. The hierosgamos is not a merger that dissolves tension — it is a tension held to the point of transformation. This is where the alchemists were more precise than the language of unity usually is. The *coniunctio* they sought was the production of something that had not existed before, the *filius philosophorum*, which is not either parent and is not a compromise between them. That insistence — on the third that is neither — is what makes Mysterium Coniunctionis difficult and worth the difficulty.
reflection_v0_3: |
  The conjunction is the point. Not the king alone, not the queen alone, but the moment of their meeting — and von Franz insists that this meeting names something real in two registers simultaneously, not metaphorically in one and literally in the other. Jung held that the alchemists were doing genuine chemistry while unknowingly projecting psychic content onto matter; von Franz quietly presses further, suggesting the correspondence runs both ways, that matter and psyche share a common ground where hierosgamos is not analogy but identity. Hillman would resist this — he distrusted any move toward unity as a veiled inflation of the ego's wish for wholeness. But the tradition von Franz is transmitting asks us to hold the tension without resolving it: the sacred marriage is not a symbol for something else; it is the thing itself, seen from two sides. The question this leaves is whether you can let an image be fully real without needing to know which side of it you're standing on.
